Be it known that I, O. SAGE, of Wellington, in the county of Lorain, andStateof Ohio, have invented a new and useful Improvement inl Cheese Vfl-ts; and I do hereby declare that the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in Which- I Figure 1 is a vertical longitudinal section of my improved cheese vat, taken through the line yy, iig. 3.

Figure 2 is a horizontal section of the same, taken through the line Se x, fig. l.

Figure 3 is a vertical cross-section ci' the same, taken through the line z z, l.

Figure 4 is a horizontal section of the heater, taken through the line :c x', iig. l.

Similar letters of reference indicate like parts. i

My invention has forv its object to furnish an improved cheese'vat, by means of which the heat applied to the milk box may be regulatcdas desired, and the performance of the various operations necessary in the preparation of the curd greatly facilitated; and it consists, first, in the combination of the milk box with the hinged frame, to which it is attached, and with the water box, in which it sets vsecondin the heater, constructed as hereinafter described, in combination with the Water box, and with the reservoir into which the heat escapes when shut ofi' from said'watcr box; third, in the combination of valves, constructed and operated as hereinafter described, withlthevwater box and with the pipes 'of the heater; and, ourth, in the combination of the hinged feet .with the water box, the whole being constructed and arranged as hereinafter more fully described.-

A is a frame, hinged to the upper edge of one end of the Water box B, as shown in iig; 1. lThe side pieces al and E of this frame are of the same length as the water box B, but .the end piece a3 is set'iny a little, as shown in fig. 1, so as to leave a vent, iiue, or opening between theend of the frame A and the end of the'boxB for the escape of steam or surplus heat when required, and also for the introduction of water into said box B. This opening is closed by a block or cap, C, as shown in iig. 1. To the upper edgeof the frame'A is attached the inilk box D, which ,mayhang suspended in the water box B, or Vits bottom may rest upon blocks, E, or other supports, F, placed in the bottoms of said water box B. The box D is made of a less size at the bottom than :it the top, so that the heated water in the box B may have free circulation all around it. At one end ofthe box D is placed a strainer, Gr, which keeps the cul-d from running off with the whey. From the lower edge of lthe end of the box D, in the rear of the strainer G, a small pipe, H, leads out through the end of the box B,

by means of which 'the whey can be drawn oli when required. This pipe should be furnished with a stop-cock, should pass through the end of the box B water-tight, and should be set in suoli a direction that it will out of and into the hole in the box B upon the raising or lowering of the box D. The water box Bis simply a rectangular wooden box, and it is furnished with a discharging pipe, I, and stop-cock for drawing off the water when required. Two, J and K, ci' the legs that support the cheese vat are made shorter than the others, L, and to these short legs J and K, or to thc bottom ofthe water box B, are pivotcd supplementary legs, M and N, connected by a cross-har, O. When these logs M and N are in the position represented in the drawings the vat stands square and firm g but when it is desired to draw ofi` the water or whey, by swinging back the legs M and N, this end of the rat may be lowered so as to permit the water or whey to run off freely. The body P1 of ol' the heater P is made of sheet metal, and the ends P" and P3 of cast metal. i Through this heater, from end to end, run three ilucs, P, l, and lm; the lower one, P, of which is the larger, and in it is built the fire. The rear ends of the tlues P* and P5, and the front ends of the ilues P5 and P, are connected by hollow caps, P7 and P5, so that the smoke and heat from the llire pass from the ilue l to the iiue P5, from the iiuc P5 to the llue PG, and thence into thelchimney through the pipe R. The space around the iues is filled with water, and said spa-ec is connected with the interior of the water box B by two pipes, S and T. As the water in the heater is heated by the lire it rises through the pipes and T into the water box B, the colder water from which passes back into the heater,l thus distributing the heat equally around all sides of the milk box D. l/Vhen the milk has been sutliciently heated, the communication between lthe heater P and the box.B is cut oft' by the valves U, which cover the mouths of thepipes' S` and T, the connecting-bar l of which is pivoted to the bottonrof the box B, and is kept in place by the guardsA 2, as shown in hg. 3. To one end of the bar lis attached si rod, 3, passing up ,between the boxes B and D, and out through the end of thelbrox B, as shown in figs. 1, 2, and 3, by means of which the valves U are operated. When the valves U are closed so vthat the heated and expanding water can no longer pass into the box B it escapes through the relief pipe V into the reservoir W, so that it is not necessary tolet the fire in the heater go down, and thus, when the curd is ready for scalding, a. quick heet erm be obtained.

I claim as nemend desire to secure by Letters Patent- The arrangement of the vitive U and rod 3, in combination with the box B, in the manner and for the purpose herein specified.

ORRIN SAGE.
